fixed_point math request
by Yashin Evgeny 17 Apr '06

17 Apr '06

Hello. Fixed point computation appears too often on an embedded systems, but it seems that implement bug free class too complex (i found a lots of implementations in internet but all of them have 2 issues - either they have an computations bugs and precision loss either they not template). That's why it will be good if in Boost appear standart fixed point library. I assume, that interface should look like these: template< typename T, int N > class fixed_point { .. }; where T - set for us bitness of the variable, and signed/unsigned flag, and N - a number of bits for fractional part of number. of course, for T - best to use types like: uint32, int32 and so on.. or change interface on something like: template< bool signed, int number_all_bits, int number_fract_bits > class fixed_point { .. };

new library class offer
by Yashin Evgeny 17 Apr '06

First of all, if this is a not correct mailing list, please forward the letter to a correct. Thank you. Well.. Consider this code: struct LibraryClass { Object* create_object(); void push_in_stack_object(Object* ); }; In this case library user meets with ambiguity, should him destroy this pointers after using these methods, or not. I just thought out some very simple and small wrapper class, and name it intact_ptr<> which the only way to say library user, that this pointer user should not delete after using (in case of create_object method) or library will not own the pointer (in push_in_stack_object method). It seems that sometimes it's useful. Also this class can decide another pointer related problems, like unwantable increment/decrement operations, pointers equality comparing and so on.

Making the core > language fancier will only make this problem worse. Concepts in the language allow things that aren't currently possible with C++98. For example, standard algorithms of the form: fn( Iterator first, Iterator last ) fn( Iterator first, Iterator last, Functor f ) cannot have overloads (in C++98) taking containers/ranges: fn( Iterator first, Iterator last ) fn( Iterator first, Iterator last, Functor f ) fn( Range rng ) fn( Range rng, Functor f ) as the last overload is ambiguous. Concepts will allow this to be resolved as a Functor will not match the Iterator requirements :). > While, the commitee is at it - how about re-visiting two-phase lookup. > Apparently there are enough implementers skeptical about it that > they've declined to implement it.

Two-phase lookup has been implemented by a growing number of compiler vendors. The reason why some vendors choose not to implement this is that it will break (a lot of?) existing code. > So its seems to me that there are a number of issues more > important/urgent than the ones currently being focused on. I, for one, like concepts. They also help simplify the implementation of functions like std::distance as they remove the need to use iterator_traits and the iterator categories that clutter implementations and make them harder to read. - Reece _________________________________________________________________ Express yourself instantly with MSN Messenger!

What about when you want to have a different character traits or allocator type for the string you are converting to? > But then you're still limited to basic_string. Can't you make one that > can use other containers? Interesting. However, I would say define it as "to_string< StringT >( x ) will convert the object x into a string of type StringT, provided that char_type< StringT >::type returns the underlying string type of StringT and StringT can be constructed from a pointer to that type." This would then allow you to define one for ATL::CStringT< CharT >, QtString or whatever other string type you want to use. You could then use it to do things like: list.AddItem( to_string< ATL::CString >( data.string )); // std::string --> ATL::CString qtlist.AddItem( to_string< QtString >( 10 )); // int --> QtString Without the template, it is difficult to do this. - Reece _________________________________________________________________ Express yourself instantly with MSN Messenger!

I am also working on implementing to_string and string_to :). Maybe we could combine our efforts and get to_string/string_to into Boost. At the moment, my versions don't have locale support and string_to isn't returning optional<T>, although I am working on it. They can be used like this: print( boost::to_string< char >( 10 )); // returns std::string print( boost::to_string< char >( 10.01 )); print( boost::to_string< wchar_t >( 10 )); // returns std::wstring print( boost::to_string< wchar_t >( 10.01 )); and: print( boost::string_to< int >( "10" )); print( boost::string_to< float >( "10.01" )); to_string currently looks like this: #ifndef BOOST_CONVERSION_TO_STRING_HPP #define BOOST_CONVERSION_TO_STRING_HPP #include <sstream> #include <string> namespace boost { namespace detail { template< typename String > struct converter { typedef String type; }; template<> struct converter< char > { typedef std::string type; }; template<> struct converter< wchar_t > { typedef std::wstring type; }; } /** @brief Represent the contents of an object as a string. * * @param value The object value to convert to a string. * @return The string representation of that object. */ template< typename String, typename T > typename detail::converter< String >::type to_string( const T & value ) { typedef typename detail::converter< String >::type string_type; typedef typename string_type::value_type char_type; typedef typename string_type::traits_type char_traits; typedef typename string_type::allocator_type allocator_type; std::basic_ostringstream< char_type, char_traits, allocator_type > converter; converter << value; return converter.str(); } } #endif and is in a form I am reasonably happy with. The string_to implementation I am not yet happy with, but looks like this: #ifndef BOOST_CONVERSION_STRING_TO_HPP #define BOOST_CONVERSION_STRING_TO_HPP #include <sstream> #include <string> namespace boost { template< typename T, typename CharT, typename CharTraits, typename Allocator > T string_to( const std::basic_string< CharT, CharTraits, Allocator > & str ) { std::basic_istringstream< CharT, CharTraits, Allocator > converter( str ); T value; converter >> value; return value; } template< typename T > T string_to( const char * str ) { std::basic_istringstream< char > converter( str ); T value; converter >> value; return value; } template< typename T > T string_to( const wchar_t * str ) { std::basic_istringstream< wchar_t > converter( str ); T value; converter >> value; return value; } } #endif - Reece _________________________________________________________________ Express yourself instantly with MSN Messenger!

[hash] Return type of fpclassify on gcc 4.0.1 on Darwin/OS X
by Daniel James 16 Apr '06

16 Apr '06

The hash floating point tests are failing on Darwin. Looking at the error (http://tinyurl.com/qoehb) it appears that when called with a long double, fpclassify is returning a value that isn't FP_ZERO, FP_INFINITE, FP_NAN, FP_NORMAL or FP_SUBNORMAL. But according to: http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/fpc… those are the only values that it can return. I've been reading up about OS X's long double implementation but can't find any mention of fpclassify. So maybe I just shouldn't use it on this platform. Please can someone with access to the platform look into this? Daniel

What if you have something like basic_string< char, case_insensitive< char > >? Or define a different allocator? You could have: typedef typename traits::char_type< StringT >::type char_type; typedef typename traits::char_traits< StringT >::type char_traits; typedef typename traits::allocator_type< StringT >::type allocator; std::basic_ostringstream< char_type, char_traits, allocator > os; os << x; return StringT( os.str().c_str()); > template <typename T> > std::string to_string(const T& x) { return basic_to_string<std::string, T> > (x); } That is similar to what I initially came up with. > template <typename T, typename SequenceT> > T from_string(const SequenceT& seq) { > T v; > myistream<SequenceT::value_type> is(begin(seq), end(seq)); > is >> v; > if (istream_failed(is)) throw invalid_argument("from_string"); > return v; > } People in this discussion have expressed a dislike of throwing exceptions on conversion failure w.r.t. lexical_cast.

Yeah. Others have requested this for lexical_cast. I was planning on adding versions which take a locale as a second parameter, but haven't gotten around to it yet. - Reece _________________________________________________________________ Express yourself instantly with MSN Messenger!

[Boost-bugs] [ boost-Bugs-1471025 ] from_ftime incorrectly processes FILETIME filled with zeros

Bugs item #1471025, was opened at 2006-04-15 14:15 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1471025&group_… Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: date_time Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Jeff Garland (az_sw_dude) Summary: from_ftime incorrectly processes FILETIME filled with zeros Initial Comment: using namespace boost::posix_time; using namespace boost::gregorian; FILETIME ft; ZeroMemory( &ft, sizeof( ft ) ); ptime pt = from_ftime<ptime>( ft ); if ( pt.is_special() ) { // Never fall into this branch! std::cout << "ERROR"; } else { // Exception: boost::gregorian::bad_year std::cout << boost::format("%1%") % pt.date().year(); } I suppose that when FILETIME is filled with zeroes, from_ftime() should return not_a_date_time. But it does not do this. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1471025&group_… ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
